Abstract
A data display/input method for a CNC apparatus without necessity of using a personal computer which has been served as a relaying device between the CNC apparatus and a host computer and also as a display device, and also capable of constructing an FA network system at low cost. A display screen of the CNC apparatus is split into first and second display areas so that information transferred from the host computer to the CNC apparatus is displayed in the first display area while information inputted to the CNC apparatus by the operator is displayed in the second display area. Display attributes in the CNC apparatus are switched in accordance with display attributes specified by the information transferred to the CNC apparatus from the host computer, whereby restrictions on a data display of the CNC apparatus are removed, permitting text data and graphic data to be displayed.
